WATER-CLOSET.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed December 24, 1908. Serial No. 469,107.

To all whom it may concern:

Be it known that I, WILLIAM GORDON MILLER, a citizen of the UnitedStates, residing in Ross township, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inNVater-Olosets, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention consists in an improvement in water closet bowls and isdesigned for the purpose of providing a construction in which theconduit leading from the bowl forms a siphon with a removable coping andin which the construction is adapted to provide for easy connection orseparation of the parts, but principally to permit of the removal of anyobstruction of the conduit. The device embodies a separable elementadapted to operate with the upper terminal of the waste conduit to forman air and gastight siphon and trap, such element being so constructedthat it may be readily and easily inserted or withdrawn and which willcooperate with the fixed portions of the bowl and its conduit to notonly provide an efficient trap structure, but to permit of complete andsuccessful flushing.

In the drawings :-Figure 1 represents a central vertical sectional viewthrough a bowl made in accordance with my invention. Fig. 2 is a planview of Fig. 1. Fig. 3 is a sectional view similar to Fig. 1 but showingthe detachable water-seal portion removed. Fig. 4 is a detail sectionalview of said portion.

2 represents the bowl which, in its entirety, is preferably made in asingle piece, of any suitable material, provided with a base 3 forsupporting it upon the floor, a main inner cavity 4, a seat opening 5 atthe front portion, and at the rear ortion with a downwardly extendingcon uit 6. As shown said conduit extends upwardly within the bowl cavityat its rear portion, a sufficient distance to always maintain the watertherein at the desired level, as indicated in Figs. 1 and 3, while abovethe said conduit is an enlarged opening 7, which may be rectangular asshown, or of any other suitable design. The conduit may lead downwardlyas shown, or may be of any other preferred design.

It will be understood that the bowl is provided with a suitable supplyconnection as at 8 for the water, which may pass downwardly into thebowl in any desired manner as by the conduit S) from the rear portionand through the hollow roll top 10, from which it passes downwardly intothe interior, as is commonly practiced in devices of this character.

11 is a removable coping, of shell form, having a hollow interior,adapted to be inserted downwardly within opening 7, as in Fig. 1, toembrace the upper portion of conduit 6, the walls of the copingextending downwardly into the bowl chamber below the top of the conduitas shown, and having a transverse air-tight partition 12 sufficientlyabove its lower edges to permit ample clearance .for the siphoning flowfrom the bowl to the conduit. The coping 11 as in Fig. 1, is providedwith a lifting handle 13 of any suitable kind with supporting flanges1-1 interfitting with the upper portion of the bowl to make a tight fitthereon; or the coping may be made as indicated in Fig. 4:, with aremovably inserted top portion 15. With either construction, uponflushing, the water and contents of the bowl will pass upwardly withinthe coping 11 and downwardly through conduit 6 and outwardly to thesewer, by siphoning action, the bowl again re-filling with Water afterthe operation, in the well known manner.

If for any reason the conduit 6 or pipe below becomes congested orobstructed, the coping 11 may be withdrawn and the obstruction removedby inserting any suitable implement, its facility for such purpose beingdue to the clearance upon removal of the coping.

An advantage of the partition 12 is that it also provides a bottom forthe up er chambered cavity of the coping, where y it may be used as areceptacle for utensils, etc.

The exact construction, arrangement or proportion of parts may bechanged or varied by the skilled mechanic, but all such changes are tobe considered as within the scope of the following claims.

Vhat I claim is 1. In an excrement bowl, the combination of a main bowlhaving an upwardly extending integral outlet conduit, and a surround ingcoping with an intervening space, forming with the bowl and its conduita dissectible siphon, substantially as set forth.

2. In an excrement bowl, the combination of a main bowl having anupwardly extending integral outlet conduit, and a surrounding copingwith an intervening eccentrically located space, forming with the bowland its conduit a dissectible siphon, substantially as set forth.

3. In combination, an excrement bowl having a main bowl cavity and anupwardly extending integral outlet conduit projecting into the maincavity and at one side thereof and having an upper copingmeceivingaperture, and a coping adapted to be fitted thereinto and surroundingthe upper end of the outlet conduit with an intervening eccentric allyarranged opening, providing a dissectible trap or siphon structure,substantially as set forth.

4. In a device of the class described, the combination with a bowlhaving an outlet conduit extending upwardly into the bowl cavity, of acoping inserted downwardly into the bowl cavity and provided with atransverse partition and extended lower walls adapted to embrace theterminal of the conduit with an intervening space, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
